IMPROVEMENT IN MACHINE :con MAKING conn.

The Schedule referred to in these Letters Patent and making part ofthesame.

To all whom it ma/y concern:

Be it known that I, HARRIS BOAR'DMAN, of Lancaster, inthe State ofPennsylvania, have made certain Improvements on Machines for MakingGord; and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings,making a part of 'this specification, in which- Figure l is aperspective View of the parts in position.

Figure 2, an enlarged view of certain parts, embraf cing a portion of myimprovements.

Figure 3 illustrates the top of the main shaft, with my centralizngadjustable guides.

Figure 4 is a plan view, showing the flexible stationary driving-beltfor the bobbin-supporters 4.

Figure 5 is a vertical section of parts of the mechanism shown in iig.l.

Figure 6 illustrates a modification of parts, having adjustable arms l,instead of the circular disk 1, shown inthe other iigures.

The nature of my invention consists in the application of adjustablecentre-guides on the head of the main-shaft stand, and an arrangement ofdevices to stop the' machine when a thread breaks, and minor iin--provements to perfect the cord-making machine.

To enable others skilled in the art to make and use my invention, I willexplain certain parts which are not new, and in the claim conne myselfto what I deem novel and patentable.

The central shaft E has its appropriate step and bearings. s.

My improvement on this is mainly conlined to its top or head, G.

Fig. 3 shows the top referred to, two plates, g, made adjustable on theflange, by means of a slot and headed screw, h, together with a third,bent in the form of a spring, g', also adjustable, the end of which, inconnection' with the terminal points of the other two plates, g, jointlyform a central guide, for the passage of the finally-united strands ofthe cord as it comes from the apex of the central pieces, heretofore inuse on the top of the shaft.

Ordinarily, much annoyance is caused by the clamping of the cord whendrawn to one side, as is the case when the tension-twist on the pulleyor horizontal shaft C is not in a vertical line.

The spring-piece g is designed to yield and permit a knot to passthrough, and again resume its position. Jointly, they hold the .cord-tothe centre, and prevent a side draught on the loose apical pieces, andgreatly aidfin'a uniform delivery of the cord to the reel, and help tomake better work.

Fig. 2 illustrates a lever, p, having a hook on the inner end, around orover which the thread from the bobbin passes as it entersv a perforationunder the flange of the collar or head that surrounds the bobbin-shaftsN. vThis elbowed lever phas its outer end made sufficiently weighty tocause it to drop when the thread breaks which holds it up. A slotted lugcontines it by a pivot, shown. Each thread from the bobbins has its ownlever p.

In .order to. stop the machine when a thread breaks, each series ofbobbins has a drop-rod, K, near the edge of its circular disk or topplate 3, contiguous to the shaft E,

This rod K is sustained by a pin, X, which projects from it, resting ona flange on the upper disk l, there being an opening provided for thepin to pass through.

l When` the rod is turned, by said lever p coming in contact with anadjustable catch It on said1'od,th e pin X is brought opposite theopening, permitting the rod K to drop by its own gravity, and in sodoing actuating a lever, clutch,orbeltshipper, by any of the means j nowemployed for that purpose.

In place of the lever p, I have also tried the bent lever s, shown alsoby g. 2, which is thrown outward on its being released by the breakingof a thread, and

operating in like manner as the elbowed lever i),for l which I deem itan equivalent.

The three disks 4 which support the'bobbins are pulley-like, and form anequilateral triangle, with the main shaft E in its centre, as in othercases.

The bobbin-shafts have their step below, in the arms projecting from thedisk 2, and bearings above in the arms projecting from the disk 1,whivcharms are made adjustable horizontally by means of slots and headedscrews.

The bobbin-pulleys or supports are revolved by a stationary exible strapor belt, F, made adjustable by va splice-,fastening at one end, theother end, V f,- being carried back and attached to the side of themachine. By its use a much wider range for adjustment is per* mitted,and, for various reasons, better adapted than a rigid, annular track,with bevelled sides on the inner.

face, for expanding slightly or contracting the action of the pulleys bya vertical adjustment, which dilfers substantially in principle andconstruction, although in both cases friction imparts motion to thebobbin-supports, so as to revolve them on their own shafts, while theyare being revolved by the central shaft in unison.

I may state that in iig. 6, I show a reel, W, formed with radiating armson one side, each arm provided with a horizontal arm, having raised endsto retain the cord wound upon it. One projecting end is loose, or madeto turn out of the way, to facilitate removing the cord.

On the reel-shaft there is a strap-pulley, U, deriving motion from astrap-pulley, u, on the shaft O.

This shaft has a bevelled cog-wheel, V, operated by a screw-gear on avertical shaft, in its bearings R on the table x.

On the under side is a horizontal cog-wheel, @which meshes in a pinion,P, afiixed to the main shaft E, under its upper bearing. This main shafthasa iixed and loose pulley, and receives motion by any of the ordinarymodes `in general use. This arrangement may possess novelty in itseompaetnessand eieieney, but I do not deem them sufcient to make anyclaim; l may mention, however, that l employ tension-pins O, shown onlyin thetop ofthe bobbin-shafts N. These may Vbe inserted at dive s pointson the shaft, for the purpose of more eeo ually eonining the threads inposition around the shaft as they are drawn out and twisted What I claimas my invention, and desire to seonre by Letters Patent, is-
